The vboxhook.dll file is a Dynamic Link Library (DLL) associated with Oracle's VirtualBox, a free and open-source hosted hypervisor for x86 virtualization. This DLL is part of the VirtualBox Guest Additions package, which provides several device drivers and system applications to optimize the performance and usability of guest operating systems running inside VirtualBox virtual machines.
The vboxhook.dll file may be involved in various tasks such as seamless window integration, improved video resolutions, better mouse pointer integration, or other functionalities that make the guest operating system work more smoothly with the host system. Essentially, it acts as a hook between the guest system and the host system, facilitating enhanced integration features.
Because vboxhook.dll is specific to VirtualBox environments, it should not be found on systems that don't have VirtualBox or its Guest Additions installed. If you do find this DLL on a system where it shouldn't be, or if you experience issues with it, you may want to investigate further, as unexpected DLL files can sometimes be associated with malware or other unwanted software.
However, if you're running VirtualBox and have installed Guest Additions on your guest operating system, this DLL is generally a normal and safe component of that software package. If you experience issues with VirtualBox, the Guest Additions package can often be reinstalled or updated to resolve problems.
